LUBRIGATING APPARATUS.-

Ap'pIication filed December 3, 1925, Serial Ne. 73,011, and'in Australia November 2, 1925.

This invention relates to lubricating apparatus but more especially refers to the lubrication of axles or the ournals of wheels of any description and it has for its object the provision of means for ensuring that the journal or axle be constantly supplied with lubricant under all conditions as long as there is any lubricant in the well, thus preventing hot boxes and torn brasses.

A further object is to provide an apparatus for this purpose which shall be simple and capable of easy installation and which shall have few parts and a long life.

Accordingly there is provided a series of rollers supported centrally below the journal or axle in such a manner as to press continually against it. The rollers which are mounted upon a spindle so that they may revolve with the journal consist of spaced discs undercut so as to leave a thin rim and a thin web. They dip into the'oil in the reservoir and as they revolve they throw the oil outwards and upwards onto the journal in a continuous stream.

In the drawings a lubricator constructed according to this invention and fitted to a railway box of a well known type is shown.

Figure 1 is an end elevation showing the journal and the device and the means for keeping it in position] Figure 2 is a side elevation of same, and

Figure 3 is a plan of the device. I

he journal 4; is of well known type and housed within a box 5 of the type which has brasses of well known construction and a removable front plate (5.

The lubricating device consists of a series of rollers T mounted on or formed integral- With a spindle 8 which runs in bearings 9. L he rollers are kept against the underside of the journal by the semi-elliptical spring 10 v which bears against the bottom of the box 5 and is attached to each of the bearings 9. he spring also allows for any rocking movement of the journal relative to the box.

The spindle is kept in a central position laterally by the distance pieces 11 which bear against the parallel members 12 bolted to tl e bottom of the box, while longitudinal movement is prevented by the member 13 which bears against one end of the devlce the other end being kept against the rear of v the box 5.

The rollers 7 are provided with a thin rim and a central web and are normally half immersed in the lubricant. On the journal revolving the rollers are caused to rotate and the lubricant onrthe inner side of the rims and on the webs is thrown upwards and outwards onto the journal and in addition is transferred directly by the actual contact between the drums and the journal.

The device may be easily fitted to any type of axle boxprovided that it has means or canbe provided easily with means for keeping it in position laterally and longitudinally. For example, boxes adapted for use with the well known pad system usually.

have integral arallel members such as 12 and by providing means such as 13 for preventing longitudinal displacementthe device may be easilyvfitted, being inserted through the plug in the front of the box.

In order to prevent waste and leakage of the lubricant along the axle some sealing means of any well known type is provided.

I claim v A device of the character described including in combination a journal, a box arranged thereabout, a pair of spaced parallel longitudinally extending and vertically arranged guides on the floor of the box,

spindle, a series of rollers thereon, a pair of bearings for accommodating the ends of the spindle, opposed distance pieces projecting from each of thebearings and contacting with the inner surface of the guides, spaced arms depending from each ofthe' bearings, a bowedspring having its medial portion engaging the floor of the bearing.

with its respective ends pivotally. connected between the arms of the bearings for normally holding the rollers in yielding engagement Withthejournal, and a device secured to the inner surface of the outer wall of the box and engaging the outer end of the spindle for preventing longitudinal movement thereof, substantially as and for the purposes set forth. V V a In testimony whereof I have signed my name to this specification.
